Granted: 1992-02-11
Abstract: ABSTRACT OF THE DISCLOSURE           A stolen object location system having a base station, a location network and an object unit which is associated with the object to be located. The location system is capable of operating in a plurality of different loca-tion modes ranging from simple triangulation to LORAN.  The base station, upon being notified that the object has been stolen, will transmit a locate request message to the object unit specifying the location mode to be used and the transmission frequency of the object unit's transmitter.  An electro-nic control in the object unit will control the operation of the object unit's receiver and transmitter in accordance with the location mode and transmission frequency specified in the locate request message.  The electro-nic control will also initiate the transmission of an alarm message if the object unit loses communication with the base station, and is capable of transmitting a tattle-tale message, effectively relaying the alarm message of another object unit if the base station does not respond to the other object unit's alarm message.

Abstract: EQUAL POWER AMPLIFIER SYSTEM FOR ACTIVE PHASE ARRAY ANTENNA AND METHOD OF ARRANGING SAME                                 ABSTRACT   An equal power amplifier system (100) for amplifying a plurality of signals for transmission by an active phase array antenna (20), and a compact plural level beam-forming network (98) for forming a plurality of such signals, for example on excitation patterns for frequency scanned virtual beams, are disclosed. The amplifier system uses at most only a few sizes of power amplifiers (130, 134) to amplify efficiently numerous signals having significantly different amplitudes. This is accomplished by distributing the task of amplifying signal pairs (Ai, Bi) composed of one large amplitude signal and one small amplitude signal to an equal power amplifying apparatus (130; 230), which includes two hybrid couplers (236, 238) and two equally sized power amplifiers (232, 234). The first hybrid coupler (236) divides the two signals (Ai, Bi) for input into the two power amplifiers. The second hybrid coupler (238) receives the intermediate amplified signals from the power amplifiers and through constructive and destructive interference produces amplified output signals (Ai*, Bi*) corresponding to the input signals. Also disclosed is a method for properly selecting pairs of signals from an amplitude distribution (200; 202) for application to such equal power amplifying apparatuses of the amplifier system in order to operate the power amplifiers therein at or near peak efficiency. The beam-forming network (98) is arranged on two levels to simplify interconnection of the selected pairs of outputs of its line summers (176) for input into the equal power amplifier system. The amplifier system and beam-forming network may be used together, for example, in the transmit antenna system of a geosynchronous satellite (10) or mobile earth station.

Granted: 1991-03-26
Abstract: ABSTRACT OF THE DISCLOSURE    A method and device for installing a cable, more in particular a glass fibre cable, into a duct of a channelization system, the consideration which has led  to this being based on the fact that the dragging working, considered from the cable inlet end, as caused by a flow of compressed gas effected in a relevant duct portion will increase according to a non-constant function and, dependent on the geometry and the length of the duct portion, can be insufficient over the initial part of it to compensate the friction forces exerted on the cable locally, According  to the invention it has now been suggested to fulfil such a compensation function by exerting on the cable a pushing force working extend-ing to the point where the dragging working will be sufficient to compensate the friction forces.

Abstract: Abstract of the Disclosure A method and apparatus for drilling subsea wells in water depths exceeding 3000 feet (preferably exceeding 4000 feet).  Drilling mud returns are taken at the seafloor and pumped to the surface by a centrifugal pump that is powered by a seawater driven turbine.  A low-differential pressure rotating head  seats  in  the upper  tapered portion of the  longitudinal throughbore of an upper stack package which is attached to the top of the blowout preventer stack and seals against the drill string as it is run in and out of the borehole.  The method and apparatus of the present invention enable higher mud weights to be used than can be used in conventional techniques which allows kicks to be more easily controlled, fewer casing strings to be run, and overall drilling time reduced by up to 40%.

Granted: 1991-09-17
Abstract: Abstract POWER SUPPLY      Arc discharge lamps driven at frequencies in excess of 20kHz may exhibit the phenomenon of 'acoustic resonance' in which longitudinal and lateral acoustic waves are supported in the arc tube.  This is a problem because the acoustic wave may give rise to an instability in the discharge arc, causing it to stretch or gyrate and invariably to extinguish.  In some cases damage may be caused to the arc tube.     A power supply suitable for an arc discharge lamp (1) comprises a drive circuit (10) arranged to supply voltage to the lamp (1) and control means (20) for causing a characteristic of the voltage to vary, with time, in accordance with a pseudo random sequence in order to reduce, or eliminate, acoustic resonance in the lamp (1).

Abstract: Abstract In a reel-change device provided for feeding high-performance packaging machines with web-like packaging material wound to form reels, two working journals are fed alternatively with ("full") reels, whilst the other working journal carries the working reel running off in the meantime.  The new reels are extracted from a reel stock by means of a transport arm with a transport journal and, as a result of pivoting to one side or the other, are brought into a position equiaxial with one or other of the working journals.  When there is correct alignment, the reel is pushed onto the empty working journal. For this purpose, the transport arm is pivotable and can be shifted axis-parallel relative to the working journals.
